Liked it. Good joke, good animation. I see from the comments that people are complaining about a background. I think the all white background just makes the movie simpler. It is a simple joke, no reason to have the background absolutely blind us with colors.

I liked the joke, and the graphics were good (though a background rather than blank white would have been nice). The fact that there are no voices is good, because that would ruin the entire thing (there are too many animals talking already). Overall, I liked this, keep up the good work... and add some backgrounds while you're at it. :)
